Abstract
According to a preferred embodiment of this invention, the exterior surface of an evaporator carries a coating of dried paint resistant to microbial growth and suitable for forming an adhered layer on cooling surfaces of an air conditioner. This paint comprises a pigment, a liquid, a binder to promote formation and adherence of the coating after the paint is applied and dried, and a metallic constituent which inhibits microbial growth. Preferably, the metallic constituent is inorganic and includes one or more of: copper, cupric carbonate, cuptic hydroxide, cuptic oxide, cuprous oxide, silver, silver oxide, zinc oxide, and zinc peroxide. The coating is preferably applied to the integral core after assembling and brazing the several plates and fins of the core.
